@citfta
Thank you as well

@ All readers

Some of these designs result in more mechanical
work out than is input.

See for your self.

Here the TinMan works on Floor's inspiration [as always ..shared with permission]

https://www.youtube.com/watch?v=KhyfD1GiCXU
much Gratitude [I hope its OK to post it here in this thread , wasn't sure which one of your topics was best ?]

Floor you are a true inspiration ![as is the TinMan

Respectfully submitted
Chet K////Edit// I see TinMan added Vids to your topic here https://overunity.com/18137/newtons-magnets/msg536314/#new // maybe if you are interested we could ask Stefan about giving you a Moderated builders board or ?? to keep your topics clean [example remove this misplaced post ?]

Thank you Ramset !

I have never resorted to moderation on any of my topics, only threatened to  do so.
I will consider it.

Thanks again Tinman.
Be advised that rotary designs are dicey at best.  A failure in one of them might reflect
badly upon investigations of the strictly linear designs.
We need to not be concerned with conservation of momentum at this point in the process.

Yes, i hear you.
I will make sure that everyone knows that the two are different,and one should not answer for the other.

Look, ferromagnetic particles in Brownian motion, if placed in a magnetic field. You must take an orderly motion. Reduced entropy. Different forces will act on a particle moving along the field line and across the magnetic field line. I'm right?

@Ramset

Moderation could get to be a big job.  Hopefully not. I think Its a good suggestion.

Deleations should  be done only to keep the topic on topic, no punishment element.

Five conditions I would like to see met. (Good Luck)

1. Since the topic is on a "floor design / designs" then the design should be followed as closely
as is reasonable / possible.

2. New designs / major "improvements" / innovations be presented on a separate topic.

3. I would want to see all deleted materials posted in their order of appearance,
to a separate topic.

4. That the deleted material topic, is available for any member to read / comment in.

5. No discussions of / re posting of deleted material on the main topic, once
they have been deleted


I can't take on the job.  I have too much on my plate at this time.
Some one else please ! (maybe Tin Man ?)


@All readers

I'm sure you will give them  rigorus due dilligence and testing, but  please resist the temptation to do improvements at this time.  These designs are my babies.

@Tinman

Linear designs have the potential for power via brute force.
Rotating designs have the potential for power via high speed.

Below is a topic on a few rotating designs.

Here is a short video showing my build of Floor's rack 3 design from his PDF.  As he has said it must have pretty accurate alignment before it will work properly.  But it can be made to work as you can see in the video.  The magnets in the video are just cheap magnets from Lowe's.  After mounting them I found the strength varied some making the adjustments a little harder.  A gauss meter used to help match up the strength of the magnets would probably be a help in making a better build.

@ CITFTA

Pretty good results !

I hope you made your test bed easy to modify

Two outer magnets tend to overpower a single shield magnet.  Where as, an over sized (broader)
shield magnet doesn't adversely effect the shielding but instead (up to a point) improves it.

Your shielding would be improved by the use of a shield magnet that is about twice as broad as the one you used
                   or
2 magnets as below (this works just fine).

Also note that,  when using a broader shield magnet, the fine tuning / adjusting,  is easier and can be less precise.

Thanks for the suggestion Floor.  Do you know if a thinner shield magnet would still work as a shield?  I am thinking that would allow the rack magnets to get closer together so they would have more repelling force when the shield magnet is removed.  I can fairly easily make changes to my test bed as everything is mounted with screws and assembled with bolts and nuts.

@ citfta

Before you tear it down you might want to try to determine what if any problems exist for the setup.
I found that when two magnets are pushing apart at close proximity there is some additional force required to remove the shield.
When the magnets are operated in attraction the shield would need more force to insert.

You might try a thin neo for the shield but it could also destroy the ceramic magnets if too close.

Nice sturdy setup though.

Hi Carroll,
can you make some basic measurement of the forces x distance?
I like how you make them moving synchronously with the roller.
